To all whom it may} concern Be it known that I, HERMTAN A. Baconnnus, a citizen of the United States, residing at Woodward, in the county of Woodward and State of @klahoma, have invented new and useful Improvements in Grease Cups, of which the following is a specification.

This invention relates to lubricators for vehicle axles and'has for its objects to provide a device of this character which may be readily connected with the hub of the wheel and arranged in open communication with the axle; one which willbe positive in ac-' tion, simple, strong and durable, and one which will insure the maximum discharge.

of the lubricant from the container.

In the drawing forming a portion of this application, and in which lilre characters of reference indicate similar parts in the several views :Figure l is a side view of a vehicle wheel showing the application of the lubricator thereto, parts being shown in section. Fig. 2 is a similar view showing the follower in a lowered position. Fig. 3 is a section through a portion of the cup and through the feed tube showing the manner of connecting the latter with the former.

The vehicle wheel 1 herein illustrated is of the usual well known construction, the hub 2 thereof having a radial threaded passage 3 therein which opens directly into the box 4 so that the lubricant may be fed directly to the axle 5.

' passage 8 in the substantially spherical bottom of the cup or lubricant container 9, being upset at 10 against the inner wall of said bottom. An integralnut portion 11 of the tube bears against the external walls of said bottom whereby to cooperate with said upset portion 10 in secm'ely connecting the cup with the tube, as. is evident. From said sp erical bottom of the cup the cylindrical side walls 12 extend, being exteriorly threaded to receive the correspondingly threaded internal side walls 13 of a combined follower and cap 14. Thc-saidfollower 14 has its head 15 provided with a threaded passage 16 in which is adjustably mounted a follower screw 17 to which is secured a follower head 18 of substantially semi-spherical configuration whereby to conform exactly with the curved internal walls of the cup bottom on one adjustment of the screw. It is also stated that the head 18 has a transverse diameter equal to the internal diameter of the cup whereby the former can move freely in the latter. The head 18 is provided with a fiat surface 19 which may be brought to bear against the head 15 of the cap is on another adjusted position of the screw 17, as shown in Fig. 1. In thisgnanner it is seen that adjustment of the headlS to the last described position maximizes the lubricant containing volume of the cap 14, while adjustment of the head 18 to the first described osition insures the maximum discharge 0 the lubricant as will be understood through the fact that the convexity of said head is adapted to lie wholly in contact with the concavity of the bottom of the lubricant cup.

The nut portion 11 furnishes means whereby the tube can be quickly-connected in the passage 3 of the hub 2, while the knurled surface of the cap 14 furnishes means whereby the cap can be manually adjusted to force the lubricant into the discharge tube 7. A.

manipulating wheel 20 of the feed screw 17 may be turned by the hand to feed the follower head 18 toward the curved bottom of the cup, as the occasion may demand.

I claim A lubricator comprising a cup having a bottom ofconcavo. convex form and'cylindrical side walls extending from the bottom and extcriorly threaded throughout their length, a' discharge tube leading from the bottom, a cap provided with an internally threaded depending flange adjustably engaging the threaded walls and provided with a head overlying the upper end of the upper smooth surface normally en aging Witnesses:
